1. a) In a land-mark judgment in the Court of Appeal, in the case of Edwards v. National Coal Board (NCB), Lord Justice Asquith awarded £984 (about £25,000 in today's money) to the widow for the NCB's failure to provide adequate protection against a roof-fall that killed Mr. Edwards. The Judge said that risks should always be reduced unless the employer could demonstrate that there was "gross disproportion" between the costs and the benefits. Explain the term "gross disproportion" and comment on how it is applied in the UK. [10] Marks) b) Explain the meaning of the phrases "So Far As Is Reasonably Practicable". [10 Marks) c. Section 2 (sub-section 2) of the Health and Safety at Work Act etc 1974, the duty is qualified each time with the words "so far as is reasonably practicable", Why? d. Marks) [Total 25 Marks) 2. a) With the aid of a diagram, explain the relationship between the key elements of the health and safety management system in HSE's 'Successful Health and Safety Management' (HSG65 or similar). (10 Marks) (b) In 1993, the original Management of Health and Safety at Work Regulations (sometimes referred to as the Management Regulations) came into force as the principal method of implementing the EC Framework Directive (89/391/EEC) in the United Kingdom. These regulations had a significant impact on risk assessment in industries like rail transport, power generation, chemical plants etc. i. Explain the phrase "Risk ASsessment". [6 Marks] ii. The Health and Safety Executive in the UK have development an approached for helping to determine the acceptability of risk. This "Tolerability of Risk" framework has 3 risk categories, explain each of the following; 1. Negligible 2. Tolerable risk 3. Unacceptable risk (9 Marks) [Total 25 Marks] 3.

A hazard study has identified that the combustion chamber could explode if there is a build-up of unburnt gas and air after a loss of flame event, leading to 5 fatalities. The rate of this explosion happening has been analysed to be about 0.01 per year (every 100 years). The plant has an estimated lifetime of 20 years. This could arise if the gas supply is not shut off as soon as the flame is lost. The are 3 functional safety system options being considered. ALARP Option 1: Reduces Frequency by factor of 10 (to 0.001): Costs £200,000.00 ALARP Option 2: Reduces Severity by factor of 5 (to 1 death): Costs £20,000.00 Perform Cost Benefit Analysis for the following options and justify the option that should be selected: i. Option 1 ii. Option 2 iii. Option 1 and 2 For the purpose of Cost Benefit Analysis use the Cost of single death (Value for Preventing a Fatality) of £2 000,000.00.
